So, technology management and innovation through a structured and flexible approach such as TRM is necessary. However Road mapping projects implementation and use of its advantages is impossible without identifying and prioritizing of success factors of technology road mapping. The aim of this work is using interpretive structural modeling technique to analyze the affecting factors on the success of technology road mapping. This helps improving technology road mapping process and identifying appropriate organizational policies. For this purpose, we firstly focus on literature review to extraction of technology road mapping success factors. Then, interpretive structural modeling technique is used for revealing the relation between those factors. For data gathering, 17 questionnaires are distributed among people with executive background or related working experience. The results show that the effective factors were classified in four levels. the most influencing factors are related to "commitment and support of management", "financial support" and "access to data, information and required knowledge", " appropriate participation of people ", "proper facilator" and " Accepting roadmapping ". The most influenced factors are "quality of roadmap" and "flexibility for reasonable changes by updating of roadmap"'. Manuscript profile -

Exploitation of the capabilities of the network of collaborators is a desirable option due to inability of the organization in providing the resources comprising finance, human, facilities and expertise. Reviewing the literature on CoPS and technological collaboration incorporating the kind and motivations of collaborators and organizational forms of collaboration and interviewing 18 experts of the organization, a model was developed based on TRL approach and fuzzy cognitive mapping tool. Considering the model developed, the steps of project is classified into 3 categories: Green(able to be collaborated in network), Yellow (able to be collaborated on condition) and red (unable to be collaborated). The role of the members of the network and the strategy of collaborating with them is specified as follows: R&D contract with universities and consulting agents, Educational acquisition with faculty members, outsourcing the projects intended as military service compensation, and R&D contract or research funding with knowledge-based institutions. On the other hand, the position of technology developing and designing centers is specified employing the national innovation system as an upper hand document. Validity of model is proven by checklist of good theories. Manuscript profile -

Unlike HD model which is complicated, time consuming with high processing cost, the proposed method has lower complexity and higher simulate speed. In our method, a RBF neural network is used to modify DD parameters. The modified DD model can generate simulate results of accurate HD model. The proposed method is first applied to a silicon n-i-n diode in one dimension, and then to a silicon thin-film MOSFET in two dimensions, both for interpolation and extrapolation. The obtained results for basic variables, i.e., electron and potential distribution for different voltages, confirm the high efficiency of the proposed method. Manuscript profile -

In recent years, extensive research has been conducted on the design of decimal arithmetic reconfigurable architectures. Since, on the one hand, the effective use of these architectures depends on the existence of appropriate algorithms and tools to implement the design on the hardware, and on the other hand, research on the development of these algorithms has been very limited, this paper will present methods for the automated synthesis of decimal arithmetic circuits on a coarse-grained reconfigurable architecture. The platform chosen to execute the proposed algorithms is the DARA coarse-grained reconfigurable architecture, which is optimized for decimal arithmetic. The algorithms proposed for resource allocation of synthesis include a heuristic method and an ILP algorithm. The results show that, as expected, for the limited architectural dimensions used, the ILP algorithm performs significantly (about 30%) better than the heuristic algorithm. Manuscript profile -

P MoreThe Agnosia is a neurological condition that leads to an inability to name, recognize, and extract meaning from the visual, auditory, and sensory environment, despite the fact that the receptor organ is perfect. Visual agnosia is the most common type of this disorder. People with agnosia have trouble communicating between the mind and the brain. As a result, they cannot understand the images seen. In this paper, a model is proposed that is based on the visual pathway so that it first receives the visual stimulus and then, after understanding, the object is identified. In this paper, a model based on the visual pathway is proposed and using intelligent Fuzzy Cognitive Map will help improve image processing in the minds of these patients. First, the proposed model that is inspired by the visual perception pathway, is designed. Then, appropriate attributes that include the texture and color of the images are extracted and the concept of the seen image is perceived using Fuzzy Cognitive Mapping, the meaning recognition and the relationships between objects. This model reduces the difficulty of perceiving and recognizing objects in patients with visual agnosia. The results show that the proposed model, with 98.1% accuracy, shows better performance than other methods. Manuscript profile -

Most experts recommend traveling to the elderly, the disabled, and the veterans. The main issue for disabled people is their being ignored in the Iranian tourism network. Many urban and public spaces lack the proper facilities and are hard to use. People with disabilities have less or limited opportunities to enjoy tourism activities. Disabled tourism needs particular attention since Yazd was named a World Heritage by UNESCO. This research designed a model of the factors that influenced developing disabled tourism in Yazd. Reviewing the literature, we identified 15 essential factors, which were revised and modified into 13 after interviews with some experts. Using cognitive mapping technique and interpretive structural modeling, we designed a model for essential factors. The results showed that the most critical factors in developing disabled tourism included the role of the government in promoting such tourism, a customized transportation system for the disabled, and security.

In such a city, humans are the main focus of urban planners, urban developers, and, most importantly, municipal decision-makers and executives. Therefore, here the biological, spiritual, and psychological needs of humans are the fundamental elements taken into account by urban management. This city, then, could unite urban spaces and tourists. Considering its great potentials, Yazd could be a good case for tourism development, building people-oriented cities, and improving the desirability of urban life. This qualitative-quantitative study sought to explore the feasibility of building a people-oriented city in Yazd province based on urban planning and the causal factors involved in this regard, intending to attract more tourists to this region. To this end, 14 interviews were conducted with tourism and urban planning experts, out of which 19 factors involved in building such a city were identified. The causal relationship between the identified factors was examined through a mixed-method approach, using the fuzzy cognitive mapping technique. The study’s findings indicated that educating the citizens, developing a sense of familiarity with the environment, and reducing environmental pollutions (soil, water, air) were the three most important factors for developing people oriented-cities in Yazd province, Iran.

The problem of ontology matching has been raised with the aim of creating a set of mappings between entities of ontologies. This problem is classified as an NP-hard problem. Therefore, greedy methods have been proposed to solve it in different ways. Selecting the appropriate lexical, structural and semantic similarity criteria and using an effective combination method to obtain the final mapping is one of the most important challenges of these methods. In this paper, an automatic method of matching ontologies is proposed to provide a one-to-one mapping set. This method detects primary mappings based on a new lexical similarity criterion, which is accordance with the descriptive essence of entities and combining this similarity with semantic similarity obtained from external semantic sources. By locally propagating the score of initial mappings in the class hierarchy graph, structurally matching entities are identified. In this method, property matching is examined in a separate step. In the final step, the mapping filter is applied in order to maintain the consistency of the final mapping set. In the evaluation section, comparing the performance of the lexical similarity measure compared to other proposed textual similarity measures, indicates the efficiency of this measure in the problem of ontology matching. In addition, the results of the proposed matching system compared to the results of the set of participating systems in the OAEI competitions shows this system in the second place and higher than many complex matching systems.

The tasks of an application are often represented in the form of a core graph. The cores establish a link between themselves using a communication platform and often the network on the chip. For finding proper mapping for an application, developers have proposed various algorithms. In most cases, due to the complexity, exact search methods are used to find the mapping. However, these methods are suitable for networks with small dimensions. As the size of the network increases, the search time also increases exponentially. This article, from the perspective of a heuristic approach, uses the harmony search method to decide when to connect cores to routers. Our approach uses an improved version of the harmony search algorithm with a focus on reducing power consumption and delay. Algorithm complexity analysis reveals a more appropriate solution compared to similar algorithms with respect to application traffic pattern. Compared to similar methods, the algorithm achieves 39.98% less delay and 61.11% saving in power consumption. Manuscript profile
